IMPROVEMENT IN DEVICES FOR CUTTING WASHERS.

Specification forming part'of Letters Patent No. 209,726, dated November5, 1878; application filed September 18, 1878.

To all whom it may concern:

Be it known that 1, WILLIAM F. TILToN, of

'McHenry, in the county of McHenry and State of Illinois, have inventedcertain new and useful Improvements in VVasher-Outters; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification, and in which- Figure 1 is a sideelevation of my improved device. Fig. 2 is a plan of the large knife orcutter, and Fig. 3 is a plan view of the small knife or cutter.

It consists in providing the slotted shank A with the male screw B forreception of the thumb-screw G, and in the construction of the largeknife D with the elbow d, and in the combination and arrangement of theparts, as hereinafter more specifically set forth.

A represents the shank, which is squared at the apex thereof, as usual,for reception of a suitable handle for operating the device. The shankis provided with the screw-thread B and the vertical longitudinal slotf, wherein the knives D and G are adjustable, and rigidly secured inposition by the thumb-screw O. The shank A is also provided with thesharp point 9 for piercing the material from which the washer is to becut.

The upper knife, D, is necessarily longer.

than the lower knife, Gr, upon which it has its bearings in the slot f,and it is provided with the elbow K, which projects the blade of theknife at right angles from its handle L, as a means of placing the upperknife, D, upon a different plane from the lower one, G, wherebyflexibility and facility of adjustment are practically imparted to theknives.

Thus constructed and arranged the knives do not interfere with eachother in operation, but respectively and simultaneously perform theintended work.

My invention is designed as an improvement upon the patent granted toEmery Brule, of October 11, 1875, No. 168,607 and I claim, therefore,only the specific construction shown and described.

I claim In a washer-cutter, the pointed shank or knife-holder A,provided with a screw-thread and slot, as shown, in combination withknives D and G and thumb-screw 0, all arranged substantially as and forthe purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature'in presence of two witnesses.

WILLIAM F. TILTON.
